X-One Biphase is a premium product from Tecnifibre that combines the best of all worlds. It is a string that offers the power and control of a poly string but without the stiffness.

X-One Biphase is a multifilament at core. Coated with Polyurethane and H2C (High Heat Capacity) fibres, this string reacts better than monofilament (Poly or Synthetic gut) and launches the ball in similar fashion as a natural gut. The H2C treatment which also adds to the elasticity makes this string much more durable than common multifilaments.

Colour: Natural
